I use a Pace ST50 with a TD100 soldering iron and have to say this is hands down the best soldering iron I have ever used. The tip and heating element are all one piece which contributes substantially to the heating times and small penlike size of the iron; from room temp (65F) to operational and stable at 600F, is less than 6 seconds. I can solder with this all day without fatigue and there is no heat transfer to the handle portion of the iron ... best part, it's actually made in the USA, I simply love it.

This is going to cost the same no matter where you buy it.

I have one of those, I use it primarily for coils where I'm really not that concerned with having a temperature controlled iron.

I would use it for doing header pins in a pinch, but become familiar with it first, as you will have no idea what your tip temperature is with this iron.

You have to find what works best for you, the main consideration is not getting the board hot enough to damage the surface pads, and to also not get components hot enough to damage them.

I use 60/40 solder and solder everything at 600 degrees, there is really no one set temperature as soldering techniques and skills are going to vary greatly. Some people prefer to solder at 750 degrees so they can be on the component for the shortest amount of time; best thing to do is grab an old circuit board out of some piece of crap equipment to practice on, an old VCR, computer power supply, etc...

I'd buy one if it existed.
